Working on getting the A/C going on my 86 325e - stock M20B27
Symptoms:
So far I've replaced:
Followed through steps in https://www.r3vlimited.com/board/sho...56&postcount=7 and aux fan works when jumped with either high/low switch.
compressor clutch engages when jumped with 12v
No power at pin 86 on K1 relay (key on, engine off)
Symptoms:
- A/C light on switch doesn't turn on, clutch doesn't engage, low aux fan doesn't turn on.
- Blower does work w/without A/C turned on
So far I've replaced:
- Aux fan resistor
- both high/low temp switches
- low pressure side a/c hose (had a gash + leaking)
- high pressure a/c switch (used)
- a/c switch in dash (used)
- A/C holds a charge (checking low side) and shows in the "green" zone with my refill can
